You can use similar Webflow libraries, such as Relume, on WordPress.
The WpAlpha Pattern library offers many sections, including headers, footers, heros, and even full-page patterns(full website). The patterns will adhere to the style of your WordPress theme.

Patterns on WordPress can be what components are on Webflow. Therefore the equivalent of Webflow components on WordPress is WordPress patterns, or WordPress blocks.
If youโre building Webflow with components(reusable components), you should familiarize yourself with WordPress template parts. These are the parts that populate the theme.
In Webflow you import a component, it will auto-import as a component. In WordPress you need to make that element a template part(header/footer) or as a synced pattern.
Another similar option is WordPress.com patterns. It offers wireframes of many categories, including headers, footers, testimonials, and contact.

Block plugin library
Generatepress offers a components library for its block plugin, GenerateBlocks, containing many elements, including Pricing, Testimonial, Gallery, Header/Footer, and many others.

The patterns work better with both, GeneratePress theme and the Generateblocks block plugin.
Elementor library
Skelementor offers a library of Elementor components, including headers, footers, navbars, and heroes.
